How the signal works
The signal score

A score out of 100 for how well reviewed a product is. It rises with positive reviews and with how many there are; negative and mixed reviews take points off.

So a handful of glowing reviews can’t beat a product lots of people like. No sponsored placements.

YouTube · Sprint Kitchen · Nov 23, 2025

Positive

Summary of a YouTube video

Stacks two 5-quart ceramic nonstick baskets vertically to fit 10 quarts of food without hogging counter width. Stainless steel riser racks let you layer four dishes at once, and Smart Finish syncs different cook settings so everything finishes hot at the same time. Cleanup doesn't take much effort since the removable crisper plates, racks, and drawers are all dishwasher safe. You do have to watch where you place it on the counter, though. The exhaust vents blow hot air out the right side rather than the back, so you'll need at least six inches of side clearance to avoid heat damage.

Positive

Summary of a YouTube video

Cooks french fries on the bottom crisper plate and fish fillets on the elevated rack inside the same basket. Double Stack Pro mode spreads rear-fan heat evenly across both drawers so all four layers crisp up well, and the nonstick baskets wipe clean fast. It blasts hot exhaust out the right side, though, so you can't park that side near walls or clutter.
